I've had this fone for two years. I like it though it has some very disappointing attributes. The battery cannot last beyond seven hours (from 100% to 0% ) EVEN WHEN IT IS OFF! In addition, its wifi has NEVER worked. I felt so bad about these two errors I vowed not to buy another Samsung fone again.
It was very fast when new but slowed down as I added apps( over 70!). I got rid of many of them and it is faster now.
It has nice features like great camera though. Perhaps if I were to root it it'd improve. Could someone please tell me how this can be safely done?
